The convexification concept generates globally convergent numerical methods
since such a method does not rely on a good first guess about the solution.
The convexification was originally proposed in purely theoretical works [1]}, [2]}. Its active numerical studies have started in 2017 after
the publication [3]}, which has removed some obstacles for numerical
implementations. In this regard, we refer to, e.g. [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]} for some
publications, which combine convergence analysis with numerical results. The
book [12]} summarizes results as of 2021. Note that in [7]}, [8]}, [12]} the convexification is verified on
experimentally collected data of backscatter microwaves.
